| 2013-07-29 | Implement deterministic ECDSA as specified by rfc-6979. | Werner Koch | 1 | -1/+556 | |
| * cipher/ecc.c (sign): Add args FLAGS and HASHALGO. Convert an opaque MPI as INPUT. Implement rfc-6979. (ecc_sign): Remove the opaque MPI code and pass FLAGS to sign. (verify): Do not allocate and compute Y; it is not used. (ecc_verify): Truncate the hash value if needed. * tests/dsa-rfc6979.c (check_dsa_rfc6979): Add ECDSA test cases.

| 2013-07-26 | Implement deterministic DSA as specified by rfc-6979. | Werner Koch | 1 | -0/+475 | |
| * cipher/dsa.c (dsa_sign): Move opaque mpi extraction to sign. (sign): Add args FLAGS and HASHALGO. Implement deterministic DSA. Add code path for R==0 to comply with the standard. (dsa_verify): Left fill opaque mpi based hash values. * cipher/dsa-common.c (int2octets, bits2octets): New. (_gcry_dsa_gen_rfc6979_k): New. * tests/dsa-rfc6979.c: New. * tests/Makefile.am (TESTS): Add dsa-rfc6979. -- This patch also fixes a recent patch (37d0a1e) which allows to pass the hash in a (hash) element. Support for deterministic ECDSA will come soon. Signed-off-by: Werner Koch <wk@gnupg.org> | |||||
